摘要
根据车西地区下古生界潜山的岩芯观察与稳定碳氧同位素数据,结合钻井地质、生产动态资料,划分了车西地区下古生界储层裂缝类型;研究了裂缝长度、宽度、倾角、充填等特征参数,并探讨了各参数间的相互关系;总结了裂缝特征参数与构造部位、埋藏深度、油气产量的关系。
Based on a detailed observation of the drill core samples of carbonate rocks and the data of stable oxygen and carbon isotopes in the Lower Paleozoic of Chexi region and according to data acquired from drilling, oil/gas production and geological study, the fissure types in the reservoir rocks are studied and divided in this paper. The characteristic parameters such as fissure length, width, obliquity and filling features, are studied, and the relationships among these parameters have also been discussed. Their interrelationships are summarized, which include the relationship between fissure parameter and structure position and the relationship between embedding depth and oil output.
